FLY London Women's Ylva Wedge Sandal Rocker bottom wedge gently rolls your foot forward into the next step for an easier, more stable stride. Lightweight thermoplastic rubber outsole provides traction to help keep you confident on your feet. Breathable, perforated nubuck leather upper features a lace-up closure, allowing you to adjust the fit. Flexible, leather-lined latex foam footbed cushions your steps. Slight platform (3/4) makes the 2 1/2 wedge feel more like 1 3/4 for added comfort.
